ESTA Is Not a Visa
ESTA (Electronic System for Travel Authorization) is an automated system that determines whether a traveller is eligible to travel to the United States under the Visa Waiver Program. CBP puts the distinction bluntly: an approved ESTA is not a visa, and does not meet the legal or regulatory requirements to serve in place of one where US law requires a visa.
ESTA is
- An eligibility screening completed online before you travel
- Only for the 42 passports already in the Visa Waiver Program
- The same concept as the EU's ETIAS and the UK and Canadian eTA
ESTA is not
- A visa, or a substitute for one where a visa is required
- A guarantee of entry - a CBP officer decides admission at the port of entry
- Permission to work or study in the United States
Applying under the Visa Waiver Program also means waiving your right to review or appeal a CBP officer's admissibility determination, other than on the basis of an asylum claim. That trade is part of the programme, and it is one reason a visa is sometimes the better route even when an ESTA would be granted.
The Travel History That Disqualifies You
This is the part most ESTA explainers skip. The Visa Waiver Program Improvement and Terrorist Travel Prevention Act of 2015 (Division O, Title II of Public Law 114-113) added section 217(a)(12) to the Immigration and Nationality Act. It removes people from the Visa Waiver Program based on where they have been - regardless of their nationality, their record, or the purpose of the trip.
The statutory trigger is presence, not travel. Tourism, a family visit, journalism, aid work and a business trip all count identically. The statute names Iraq and Syria directly, then extends to any country designated a state sponsor of terrorism and any further country of concern designated by the Secretary of Homeland Security - which is how the list below grew past two.
Two different dates, and CBP is not consistent about them
Eight of these countries share the statutory threshold of 1 March 2011. Cuba runs on its own date - 12 January 2021, when it was designated a state sponsor of terrorism - and CBP's Cuba guidance states that threshold explicitly. The live ESTA application, however, asks question 9 as a single nine-country question using the 1 March 2011 date for all of them. If either date could apply to you, assume you are affected and plan for a visa rather than betting on the narrower reading.
An Approved ESTA Can Be Revoked
An authorisation granted before a disqualifying trip is not protection. CBP states that an approved ESTA may be revoked at any time, and says so most directly in its Cuba guidance: if an ESTA has already been approved and it is later determined that the traveller was present in Cuba on or after 12 January 2021, or holds dual nationality with both a VWP country and Cuba, the ESTA will be revoked.
The practical consequence is the one that catches people out. Your ESTA can be valid when you book, and invalid by the time you fly, because of a trip you took in between. CBP recommends that travellers who have been to one of the listed countries apply for a new ESTA or a visa proactively rather than waiting to find out at the airport.
Dual Nationality: A Separate, Shorter List
A second restriction runs alongside the travel one and is frequently conflated with it. Nationals of VWP countries who are also nationals of the countries below are ineligible to travel under the Visa Waiver Program. This is assessed at the time you apply, and it does not matter that you also hold a VWP passport.
Note what is not on this list: Libya, Somalia and Yemen restrict you if you have been there, but holding their nationality does not by itself remove you from the programme. And the exceptions described below, which can rescue a traveller caught by the presence rule, do not apply to the dual-nationality rule at all.
The Exceptions Are Narrow
The statute carves out two categories, both requiring a determination by the Secretary of Homeland Security, and both about why you were there:
- Presence to perform military service in the armed forces of a Visa Waiver Program country.
- Presence to carry out official duties as a full-time employee of a Visa Waiver Program country's government.
Beyond those, the Secretary of Homeland Security may grant a discretionary waiver, but only where DHS determines it is in the law enforcement or national security interests of the United States. There is no separate waiver form: you apply for an ESTA and waiver eligibility is considered as part of that adjudication. Waivers are case-by-case and rare, they are never decided at the border, and they are not something to plan a trip around.
Fee, Validity and When You Need a New One
The ESTA fee rose sharply in recent years. Section 100014 of Public Law 119-21, enacted 4 July 2025, raised the statutory minimum, and CBP began assessing the inflation-adjusted FY2026 amount on 1 January 2026. Because the fee is set by statute and adjusted annually, treat any figure you read anywhere - including here - as something to confirm on esta.cbp.dhs.gov before you pay.
A completely new application, and a new fee, is required if you are issued a new passport, change your name, change your country of citizenship, or if the circumstances behind any of the yes/no eligibility answers change. There is no way to amend those on an existing authorisation.
Who Needs an ESTA (42 passports)
These are the passports our dataset records as reaching the United States without a visa but with a mandatory pre-travel authorisation. Each links to its full entry-requirements page. Everyone travelling under the programme needs their own ESTA, including children of any age, and it is required for land border crossings and for merely transiting the United States, not just for flights.
Not everyone who enters without a visa needs one: Canada, Marshall Islands, Micronesia and Palau reach the United States without a visa under separate arrangements, outside the Visa Waiver Program and its ESTA requirement.
If You Are Affected, You Can Still Travel
Losing Visa Waiver Program eligibility is not a ban on entering the United States. It moves you from the online route to the embassy route: you apply for a nonimmigrant visa, normally a B-1/B-2 visitor visa, at a US embassy or consulate. That means an application, a fee, an interview and a wait, but it is an ordinary process with an ordinary outcome for most applicants.
One practical tip from CBP's own guidance: keep a copy of the ESTA denial or revocation. A traveller affected by the 2015 Act who has imminent business, medical or humanitarian travel may request an expedited visa appointment, and the consulate may ask to see it. Granting the expedited slot is at the consulate's discretion.
Entry suspensions issued by presidential proclamation are a separate regime from the Visa Waiver Program, with their own country lists, effective dates and exceptions, and they change. If you think one may apply to you, check the current proclamation text on the Federal Register alongside CBP's VWP guidance.
ESTA FAQ
Is ESTA a visa?
No. CBP is explicit that an approved ESTA is not a visa and does not meet the legal or regulatory requirements to serve in place of one where a visa is required. ESTA is an automated eligibility check for travellers who are already visa-exempt under the Visa Waiver Program. If your passport is not in the VWP, ESTA never applies to you and you apply for a visa instead.
Can travelling to another country stop me from getting an ESTA?
Yes, and this is the single most misunderstood rule in the programme. Under the Visa Waiver Program Improvement and Terrorist Travel Prevention Act of 2015, having been present in Iraq, Syria, Iran, Sudan, Libya, Somalia, Yemen or North Korea at any time on or after 1 March 2011 makes you ineligible to travel under the VWP. CBP applies the same treatment to presence in Cuba on or after 12 January 2021. The trigger is presence, not the purpose of the trip, so tourism, journalism, aid work and a family visit all count the same.
Can an ESTA I already hold be revoked?
Yes. CBP states that an approved ESTA may be revoked at any time. For Cuba specifically CBP says so directly: if an ESTA has already been approved and it is later determined that the traveller was present in Cuba on or after 12 January 2021, or holds dual nationality with both a VWP country and Cuba, the ESTA will be revoked. An authorisation approved before a disqualifying trip is not a shield.
Does dual nationality affect my ESTA?
It can, and the list is different from the travel list. Nationals of VWP countries who are also nationals of Iraq, Syria, Iran, North Korea or Sudan are ineligible to travel under the VWP, and CBP applies the same to dual nationality with Cuba. Critically, the military and government-official exceptions that exist for the travel restriction do not apply to the dual-nationality restriction at all.
How long is an ESTA valid?
CBP states that ESTA approvals are typically granted for a two-year period or until the applicant's passport expires, whichever is sooner, and can be used for multiple trips in that window. The actual dates are shown on your approval, and CBP may issue a shorter term. A brand-new application and a new fee are required if you get a new passport, change your name, change your country of citizenship, or if the answer to any eligibility question changes.
My ESTA was denied. What now?
An ESTA denial only closes the Visa Waiver Program route - it is not a bar on travelling to the United States. You apply for a nonimmigrant visa, normally a B-1/B-2 visitor visa, at a US embassy or consulate. CBP suggests keeping a copy of the denial or revocation: a traveller affected by the 2015 Act who has imminent business, medical or humanitarian travel may request an expedited visa appointment, though granting it is at the consulate's discretion.
Do I need an ESTA if I already hold a US visa?
No. CBP states that individuals travelling on valid visas are not required to apply for ESTA, and may travel on that visa for the purpose it was issued for.
Do children need their own ESTA?
Yes. CBP requires accompanied and unaccompanied children, regardless of age, to obtain their own independent ESTA approval. There is no family application.
